Hi Mark, <Comment> I have implemented a very crude version of this. I use the IE5 DOM and with this I retrieve documents from our database using URLs that are a scaled down version of XQL (I can't say I like XPointer). For example: http://[server]/documents/article[@author='Mark']/article.xml would retrieve all 'article' objects with an author attribute of 'Mark', that are children of a node of type 'documents'. This would then be returned to the caller as an XML document, but with a stylesheet PI pointing to 'stylesheets/article.xsl'. (Replacing .xml with .htm would yield the same results but the XML and XSL would be combined for you on the server.) The problem with this is that I have to convert this request to a query on the objects in the hierarchical database in order to populate my DOM. Of course, once in the DOM I can export it as XML or transform it if necessary, so the database does look from the outside like it is one great big XML document. But although I am quite happy with this so far, I can see that you would have to code this up for every type of database, and really it should be a job for the DOM. It really needs a layer like the layer above the database-specific layers in ODBC; it would sit just below the DOM. This layer would obviously need to understand schemas, so it wouldn't be a trivial task to implement. Anyway, my original question was 'is anyone doing anything like this?' and I think the answer is 'nowhere near yet!' </Comment> <reply> This is an interesting request. Do you want us to explore a bit further your need? a) if you got a DOM interface on a RDB, would this be useful? b) if you would have a ODB with a DOM interface and that the ODB just maintain some virtual memory pages in memory. (i.e. the whole DOM is not in memory at once, only some pages are) Would this be useful?
